Problems with including files for ASP in IIS 7.5 - iis

thanks for taking the time to read this question of mine, which I'm sure is a school boy error but for the life of me, cannot see it.
I have an ASP page which has the following contents:
<!-- #include file="include.asp" -->
<%
Dim ConfigFile
ConfigFile = Left(Request.ServerVariables("URL"), InStr(Request.ServerVariables("URL"),"/framework/lib/dms/asp/"))
ConfigFile = ConfigFile & "project/config/ConfigDms.inc.asp"
%>
<HTML>
<HEAD>
</HEAD>
<BODY>
<%=ConfigFile%>
</BODY>
</HTML>
Which works when accessed as a stand-alone page, or when called via an iFrame (don't ask). However, if I add the line "include ConfigFile" the page returns a 404 error in IIS. The value of ConfigFile is "/cms/project/config/ConfigDms.inc.asp", as printed out in the body of the page.
If I add the line "include https://xxx.xxx.xxx.xxx/cms/project/config/ConfigDms.inc.asp" to replace the original include statement, it works as intended.
Now I'm sure that this is a configuration error, but either though I put the ASP setting "enableParentPaths" to true and scrip "errorsenttobrowser" to true, I'm still not getting anywhere.
I have identical code on another server running an older version of IIS and it is working fine, however, I never setup the original server and have no documentation for setting up the new server.
The ASP script which causes the 404 error looks like:
<!-- #include file="include.asp" -->
<%
Dim ConfigFile
ConfigFile = Left(Request.ServerVariables("URL"), InStr(Request.ServerVariables("URL"),"/framework/lib/dms/asp/"))
ConfigFile = ConfigFile & "project/config/ConfigDms.inc.asp"
include ConfigFile
%>
<HTML>
<HEAD>
</HEAD>
<BODY>
<%=ConfigFile%>
</BODY>
</HTML>
But this file works fine:
<!-- #include file="include.asp" -->
<%
Dim ConfigFile
ConfigFile = Left(Request.ServerVariables("URL"), InStr(Request.ServerVariables("URL"),"/framework/lib/dms/asp/"))
ConfigFile = ConfigFile & "project/config/ConfigDms.inc.asp"
include "https://xxx.xxx.xxx.xxx/cms/project/config/ConfigDms.inc.asp"
%>
<HTML>
<HEAD>
</HEAD>
<BODY>
<%=ConfigFile%>
</BODY>
</HTML>
Regards

The reasoning for getting 404 errors when trying to access a particular page, was indeed correct. A colleague of mine changed the default error messages for bespoke ones, but failed to copy the actual HTML error pages onto the server.
This meant a 500 error was detected, tried to display the 500.html page but couldn't find it and hence displayed a 404 error.....
Sorry for anyone who has spent time reading this...

How to include external .js file to ejs Node template page

I cannot find a way to include external .js file to Node ejs template. I want to put logic and data into object in external .js file, include that file to index.ejs template and pull data from it.
I tried by inserting standard way
<script src="sample.js"></script>, and it doesn't work
Then I tried ejs specific keyword <% include partials/sample.js %> and this works only for adding partials (ejs code snippets).
I inserted .js file into static directory which is defined in executable server.js, no results again.
But interestingly, including css file into ejs template classic way works fine, for example
<link href="/assets/styles.css" rel="stylesheet" type="text/css" />
Workaround would be to include external ejs file where I would put logic and data inside <% %> tags, but this is obviously a patch and not a viable solution, because ejs is not a js file. Besides, it doesn't work.
I cannot find any solution on Internet. Any hint?
Thanks
You can't.
Note: You can only pass data from .ejs file to .js file but not the other way. It won't work because .ejs is rendered on the server side while .js runs on the client side.
I am assuming you are using EJS on server side
1) You can pass an ejs variable value to a Javascript variable
<% var test = 101; %> // variable created by ejs
<script>
var getTest = <%= test %>; //var test is now assigned to getTest which will only work on browsers
console.log(getTest); // successfully prints 101 on browser
</script>
2) You can't pass a js variable value to a ejs variable
Yes, you can't: if it is on server.
Why:
The EJS template will be rendered on the server before the js is started execution(it will start on browser), so there is no way going back to server and ask for some previous changes on the page which is already sent to the browser.
A workaround with Express:
myScripts.js
module.export = {
foo() {},
bar() {}
}
Then in your app.js
var myScripts = require('/path/to/myScripts');
res.render('template', {
utils: myScripts
}); // you forgot a ')' here
then in your template.ejs
// utils will act in global scope for this file
<%
utils.foo();
utils.bar();
%>
I believe you are using it contrary to the intent.
In a controller you can define external scripts and styles you want to include like so
res.render('page-one', {
title: 'Page One',
data: pageData,
libs: ['page-one', 'utils'],
styles: ['page-one']
});
In your static assets for your app you have a js folder and a css folder
|- static/
|- css/
|- fonts/
|- img/
|- js/
favicon.ico
|- templates/
In your js folder you place the file page-one.js and utils.js
In your css folder you place the file page-one.css
In the head section of your html in the ejs template
<!-- styles included on all pages -->
<link rel="stylesheet" href="/css/bootstrap.css">
<!-- styles specific to individual pages -->
<% if (typeof styles !== 'undefined') { %>
<% if (styles.length > 0) { %>
<% for (let style of styles) { %>
<link rel="stylesheet" href="/css/<%= style %>.css">
<% } %>
<% } %>
<% } %>
Typically it is best practice to include scripts at closing body tag so they don't block page render so before the closing body tag in your ejs file
<!-- scripts included on all pages -->
<script src='/js/libs/jquery.min.js' type='text/javascript'></script>
<!-- page specific scripts -->
<% if (typeof libs !== 'undefined') { %>
<% for (let lib of libs) { %>
<script src='/js/<%= lib %>.js' type='text/javascript'></script>
<% } %>
<% } %>
</body>
When your page renders it will render the script and CSS includes automatically
The if block is in case you don't define any includes in the controller.
In your Express application you define your static and external script includes like so
Remember up above we created js and css folders inside a directory named static
// Define static assets
app.use(express.static('static'));
// included on all pages
app.use('/js/libs', express.static(path.join(process.cwd(), 'node_modules/jquery/dist'), { maxAge: 31557600000 }));
Finally, if you absolutely must include JavaScript in your template like rendering JSON data, etc. using special ejs tag <%- %>
<% if (jsonData) { %>
<script id="jsonData">var jsonData=<%- JSON.stringify(jsonData) %>;</script>
<% } %>
I was able to do that by:
serving the Js folder/file in the node app entry file like so:
app.use(express.static(path.join(__dirname, 'views/js')));
Added DOM functions in a index.js file which is in views/js folder.
Added script tag that links to the index.js file before the end body tag of index.ejs file like so:
<script scr="index.js" type="text/javascript"></script>
Note that the src in the script tag does not have "./js/index.js". I actually don't know why it works that way (same with external css stylesheet).
You can achieve it by adding the code below:
app.use(express.static(path.join(__dirname,public)));
You have to add a directory named public (or whatever you are naming) in your project folder. In that folder you can add your external JS file.
NB: the expression path.join is used to make the directory public available/accessible when you call/initiate app from outside the project folder.

Why am I not able to load a module from within embedded JavaScript?

My objective is to store some data in a module and then be able to retrieve
that data for display using embedded javascript contained in an HTML document. My code for testing this is shown in the following 3 files:
File 1: The HTML (/var/www/html/modTest.html)
<html>
<head>
<title>Module Test</title>
<% var myModule = require("/var/www/cgi-bin/node_modules/modTest") %>
</head>
<body>
<p>Color: <%= myModule.color %>
</body>
</html>
File 2: The Module (/var/www/cgi-bin/node_modules/modTest.js)
var color = "Blue";
module.exports.color = color;
File 3: The CGI Script (/var/www/cgi-bin)
#!/bin/node
var fs = require("fs");
var ejs = require("ejs")
console.log("Content-type: text/html\n");console.log(ejs.render(fs.readFileSync('/var/www/html/modTest.html','utf8')));
When I load the URL of the cgi script into my browser I get a blank page. There is an error message in the httpd error log compaining that "require" is not defined. Can anyone please tell me why this is and (more importantly) how to fix it? Thanks for any input.

you need require.js or webpack/browserify to link/pack your javascript together for client side and to load your modules with a require - otherwise you would need to include every javascript file in as a
<script src="...">
tag seperately.

Add custom view to jhipster app

I would like to add a custom view to jhipster app on index.html
I already created the link in navbar.html and added the html file on path src/main/webapp/scripts/app/custom/newView.html
<a ui-sref="newView" data-toggle="collapse" data-target=".navbar-collapse.in">
<span class="glyphicon"></span>
<span class="hidden-sm">new view</span>
</a>
When I click on the link it doesn't work. Probably it needs a custom route in angular but I can't figure out how to create it. What else should I do?
In addition to the other answer, here is another piece of information. Maybe somebody else will find it useful. I had a similar problem with a custom view but only in production. Everything was fine in dev mode. In production mode, nothing would display and I had this javascript error that read "could not resolve ... from state ...".
It turns out that my javascript file (where the state was declared) was declared like this in index.html
<!-- build:js({.tmp,src/main/webapp}) scripts/app.js -->
<script src="scripts/app/app.js"></script>
<script src="scripts/app/app.constants.js"></script>
...
<!-- endbuild -->
<!-- custom -->
<script src="scripts/app/pages/quizz/quizz.js"></script>
<script src="scripts/app/pages/quizz/quizz.controller.js"></script>
I had created the separation on purpose, just to make it easier to read. Once I moved it up to have it before endbuild, the problem disappeared. I guess this is related to how the app is packaged somehow? I haven't looked at how it does it.
I've figured it out:
I had to add a angularjs route. Created a js file
src/main/webapp/scripts/app/custom/newv.js with the following content:
angular.module('jCrudApp')
.config(function ($stateProvider) {
$stateProvider
.state('newView', {
parent: 'site',
url: '/newView',
views: {
'content#': {
templateUrl: 'scripts/app/custom/newView.html',
//controller: 'MainController'
}
}
});
});
and import the new script in index.html
<script src="scripts/app/custom/newv.js"></script>

Metalsmith static site pages are missing metadata

I've been attempting a tutorial to set up Metalsmith, and I've gotten to the end of part 1.
I've install node.js and modules. The IDE is Visual Studio 2013 with Node.js tools installed. I've put a basic structure in and I'm trying to get a single page to render with a template.
The instructions tell to put into a file the following:
---
title: Home
template: home.hbt
---
This is your first page
With a template like:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>{{ title }} | Metalsmith Page</title>
</head>
<body>
<div class="main-wrapper">
{{{ contents }}}
</div>
</body>
</html>
The tutorial says that it should render out into a html page but the result I am getting is something like:
--- title: Home template: home.hbt --- This is your first page
When I use the markdown renderer it gives
<p>---
title: Home</p>
<h2 id="template-home-hbt">template: home.hbt</h2>
<p>This is your first page</p>
Debugging the code shows that when it gets to the renderer the YAML front-matter metadata is missing. This seems to be important as the plugins use the metadata to render the page.
The key to the solution lay in the three strange charatcers at the begining of the markdown rendered page

and the YAML front-matter warning:
UTF-8 Character Encoding Warning
If you use UTF-8 encoding, make sure that no BOM header characters exist in your files or very, very bad things will happen to Jekyll. This is especially relevant if you’re running Jekyll on Windows.
Looking at the buffer loaded in Node.js showed the utf8 BOM characters.
One solution would be to make the IDE stop saving it as utf8 with BOM but for me that wasn't a viable option.
I created a workaround as a few small lines that has to be run before any other metalsmith plugin.
var stripBom = require('strip-bom');
var front = require('front-matter');
var extend = require('extend');
// **snip**
.use(function __utf8BOM_workaround(files, metalsmith, done)
{
setImmediate(done);
Object.keys(files).forEach(function (file)
{
var data = files[file];
var parsed = front(stripBom(data.contents.toString()));
data = extend({}, data, parsed.attributes);
data.contents = new Buffer(parsed.body);
files[file] = data;
});
})

YUI error: Uncaught ReferenceError: YUI is not defined

I am a jQuery user and just learning YUI. I have the following code and I keep the error that YUI is not defined. I know it is an issue with linking to the library but I'm not exactly sure what. I had someone else test my code where they had YUI held locally and it worked fine. If I need to do this, how do I obtain a copy of the min.js file? When you download a copy from the YUI site its a tonne of files...
<head>
<title>YUI3 Test</title
<script src="http://yui.yahooapis.com/3.2.0/build/yui/yui-min.js"></script>
</head>
<body>
<div id="menu">
<p>Click here to test.</p>
</div>
<script>
YUI().use('node', 'event', function (Y){
var changeText = function(e){
e.target.setHTML("<p>Now you see the test working.</p>");
}
var node = Y.one("#menu");
node.on("click", changeText);
//node.on("click", function(e){
// Y.one(node).load('menu.html');
//});
});
</script>
</body>
Thanks!
You're missing a > after </title. This may be causing the script tag not to be recognized and so it's not loading.
Here it is broken: http://jsbin.com/ubaxoy/1/edit
And here it works after adding the missing >: http://jsbin.com/ubaxoy/2/edit
I also had to change setHTML to setContent because YUI 3.2 didn't have setHTML yet. I'd also recommend you to use a newer version of YUI, from 3.9.1 up. There have been a number of great additions since 3.2.
